O Oriens

Short, sweet, and on the solstice.

“The people who walked in darkness have seen a great light; Upon those who dwelt in the land of gloom a light has shone.” (Isaiah 9:1[2])

Today is also the feast of Saint Thomas the Apostle in the old calendar.

O Oriens,
splendor lucis ætérnae, et sol justítiæ:
veni, et illúmina sedéntes in ténebris, et umbra mortis.

Englished:

O Rising Sun,
splendour of light eternal and sun of righteousness:
Come and enlighten those who dwell in darkness and the shadow of death.
